Market Constraint – the amount of customers’ orders is not
sufficient to sustain the required growth of the system.

Time Constraint – The response time of the system to the
requirement of the market is too long to the extent that it jeopardizes the
system’s ability to meet its current commitment to its customers as well as the
ability of winning new business.
